A cyberattack occurred against the Russian instant messaging service Quiet Internet Pager.
LeakedSource, a breach notification service, claims that the compromised dump contains information on over 33 million users.
After analysing the disclosed data, security specialists at HEROIC verified that the records contain plain text passwords, usernames, and email addresses.
One of the three hijacked accounts is linked to Mail.Ru email addresses, according to a detailed examination of the compromised accounts. Experts estimate that the archive was created between 2009 and 2011.
